It is the structure which provided the vortex space 5b which does not have the sawtooth-shaped uneven | corrugated 5a in the inner wall of the grinding | pulverization cylinder 5 by width.

Figure 7 is a cross-sectional view showing an assembled state showing another embodiment of the present invention, Figure 8 is a side cross-sectional view showing a partition coupling state of Figure 7, which is between the rotating body 10 and the adjacent rotating body 10 In the middle of the space 11 to be coupled to form a partition 11b through which several transfer holes 11c penetrate, and the ring barrel 5c is coupled to a ring member 5c in contact with the outer periphery of the partition 11b. to be.

The grain grinder 1 of the present invention constituted as described above is used for the purpose of pulverizing the milled products such as beans, barley, corn, and other milled products such as red pepper, and the like. The operation of the present invention and the like will be described.

In order to grind the pulverized material, first, the pulverized material, which has undergone washing or the like, is supplied to the feed hopper 15 while power is applied to the grain grinder 1 of the present invention. When the object to be grind is large, such as red pepper, it is first subjected to rough grinding before feeding.

The pulverized material introduced into the supply hopper 15 is supplied to the transfer pipe 16a and connected to the pulverization cylinder 5 by a screw 16c driven by a motor 16b which is a fixed-quantity supply stage 16. The pulverized material is injected into the input pipe 13. At this time, the air is supplied to the air supply pipe 14 provided in the input pipe 13 together.

The pulverized material supplied to the inside of the pulverization cylinder 5 with air through the input pipe 13 is connected to the drive shaft 7 rotated by the drive motor 8 in a state where the pulverization cylinder 5 is fast. The grinding is performed by the rotating body 10 to rotate.

In the case of the rotating body 10, donut-shaped side plates 10c and 10d are disposed on both sides of the upper part of the diaphragm 10b, and the diaphragm 10b and both side plates 10c and 10d are interconnected by several impellers 10e. In one configuration, when the rotating body 10 rotates at a high speed, a strong suction pressure is generated below the donut-shaped side plates 10c and 10d, and, on the contrary, the discharge pressure is increased to the top of the side plates 10c and 10d. Will occur.

Therefore, the pulverized material introduced into the pulverization cylinder 5 as described above is strongly introduced through the space portion 10f formed between the diaphragm 10b and the side plate 10c by flowing under the side plate 10c where the suction pressure is generated. It is moved so that it hits the sawtooth-shaped unevenness | corrugation 5a of the grinding | pulverization container 5, and it grind | pulverizes.

The pulverized product hit by the sawtooth unevenness 5a of the grinding barrel 5 is discharged to the upper side of the diaphragm 10b or the upper side plate 10c as shown in FIG.

The pulverized product discharged to the upper side of the side plate (10c) is moved along the guide surface (12) formed inside the cover (3) and the suction pressure as described above together with the pulverized material introduced into the inlet pipe (13) It flows in below the side plate 10c which arises. Then, the pulverized product moved upwards of the diaphragm 10b is naturally moved along the sawtooth unevenness 5a by the discharge pressure of the space portion 10f formed between the other side plate 10d and the adjacent rotating body ( 10) is moved to the space formed between.

In the case of the pulverized product moved by the rotating body 10 as described above, the diaphragm 10b has a diameter larger than that of the side plates 10c and 10d, so that the pulverized material moves to the neighboring rotating body 10. Small things move and relatively large particles are returned and regrind.

The pulverized product moved to the space between neighboring both rotating bodies 10 is moved to the drive shaft 7 side where suction pressure is generated, and the moved pulverized substance is the side plates 10c and 10d of the adjacent both rotating bodies 10. ) It is sucked downward. At this time, the suction space is narrowed by the guide plate 11a protruding from the space plate 11 below the side plate 10c of the rotating body 10 positioned at the pulverization moving direction side. The pulverized pulverized material is sucked first, and the remaining pulverized material with a large amount of pulverized particles is sucked under the side plate 10d of the first rotating body 10, which is the lower suction pressure without the guide plate 11a, to make secondary pulverization. You lose.

On the other hand, when a large amount of the pulverized product crushed by neighboring both rotating bodies 10 as described above is introduced into the space, entanglement occurs in the sawtooth unevenness 5a. Forming the vortex space 5b on the inner surface of (5) is to ensure the natural movement of the pulverized product.

As described above, the pulverized material is moved to the cover 4 in which the discharge pipe 17 is installed while passing through the plurality of rotating bodies 10 and discharged to the discharge pipe 17. In the present invention, since the spiral discharge rod 22 driven by the motor 21 is installed in the discharge pipe 17, the pulverized powder is entangled in the discharge pipe 17 to block the discharge pipe 17. Will be prevented.

As described above, the size of the pulverized particles may be determined by adjusting the movement speed of the pulverized material in the pulverization cylinder 5 using the air supply amount to the air supply pipe 14 provided in the input pipe 13. It is.

In other words, when thick particles are desired, the amount of air input is increased to increase the moving speed of the pulverized powder, and when the particles in the finely pulverized state are desired, the amount of air is reduced to reduce the moving speed of the pulverized product.

When the present invention is configured as shown in Figs. 7 to 8, the to-be-ground object to be moved in the direction of travel in the rotating body 10 is guided by the partition 11b formed in the space 11, wherein the particles are small The pulverized product is supplied to the adjacent rotating body 10 through the conveying hole 11c formed in the partition 11b, and the pulverized material having large particles is lower than the side plate 10d of the rotating body 10 on the opposite side of the advancing direction. It is sucked into the secondary grinding is to be made.

As described above, the grain grinder 1 provided in the present invention has a multi-stage rotating body 10 capable of generating suction and discharge pressures inside the grinding barrel 5 in which the tooth-shaped unevenness 5a is formed. It can be used to quickly pulverize the pulverized material continuously put in place without a screen, and it is easy to use the machine, and it can pulverize the pulverized object without fear of failure. When used for many industries, it is a very excellent invention that it is possible to grind at low cost and to provide convenience for maintenance of the device.
